isolation and characterization of six highly intrinsic fluorescent metabolites in armillaria mellea (vahl. ex. fr.) karst

six fluorescent compounds were isolated and characterized in rhizomorph of a. mellea and were presented first as: f , f , f , mf , mf and mf . these compounds differed by rf on chromatoplaque, max in uv spectra and ex, em and max in fluorescence spectra. their gc-ms analysis indicated that f has a phenolic moiety and the other five are the benzenic derivatives. f compound was more fluorescent resulting from its hydroxyl group. the difference between the fluorescent compounds of rhizomorph and hyphae suggests the participation of some of these compounds in differentiation. moreover, these compounds may have antibiotic activity against their hosts or enemies
